Question

Which of the following options are true?

1.All rhombuses are squares

2.All squares are rectangles

3.All rectangles are parallelograms

4.All parallelograms are quadrilaterals

5.All parallelograms are rhombuses

• A. 1, 2 and 3
• B. 2, 3 and 4
• C. 3, 4 and 5
• D. All of them

Answer 1

The correct option is B

2, 3 and 4

Let us analyze them:

1. Squares have all angles = 90º, which is not true for rhombuses.
2. Rectangles have opposite sides equal and all angles 90º, which is true for squares.
3. Rectangles have opposite sides equal, which is true for parallelograms.
4. Parallelograms have 4 sides, which is true for quadrilaterals.
5. Parallelograms may have unequal sides, which is not true for rhombuses.

So, only 2, 3 and 4 are true.
